Configuration:- The front to back dimension of the sash is 52mm, outer frame is 128mm and cill (built-in) options are 210mm or 150mm. Available in two profile options 'Standard configuration' and the 'Heavy duty configuration'.

Size limitations:- Maximum recommended size for standard configuration are up to 1600mm wide and upto 3000mm high. For Heavy duty configuration upto 1700mm wide and upto 3000mm high, using sash VS04 with aluminium interlock.

All outer frames are fully reinforced with aluminium, the sashes are fully reinforced with galvanised steel.

Structural strength is enhanced through the use of steel or aluminium reinforcement through the internal chambers of the profile and to further increase stability and strength all fixings and hardware are secured to the reinforcement. The vertical slider also has an aluminium interlock for the top sash which increases the rigidity of larger windows

Tilt & Turn
Tilting sashes by the means of a pivot bar, allows the window to tilt so that exterior glass can be cleaned from the inside, and a soft damp cloth is all it takes to maintain the frame. Tilt restrictors ensure the tilt mechanism works smoothly and safely.

Sash horns
A Victorian innovation, they helped shed water from the sash and covered the end grain of the wood preventing water penetration. On our uPVC sash windows they are purely decorative.

Handles & Locks
White, gold and chrome options available.

Trickle vents
Ventilation vents can be applied in the frame or in the sash, available incapacities of 2000 & 4000 (habital rooms require capacity of 8000).

Equal sight line
Fitted as standard, most uPVC windows have unequal sight-lines. This is where the glass in the opening sections appears to be smaller than the glass in the fixed part sections. To duplicate the equal sight lines of the traditional sliding sash we have created a special insert which is fitted to the non opening section to reduce its width to match that of the opening sash. Thus a more aesthetic appearance is obtained.

Low Line gaskets / weatherseals
Fitted as standard, gives the sash window a clean look, as well as improving long term weathering and thermal efficiency.
